Full textAbstract:
This study aims to analyze a phenomenal song entitled “Baby Shark” composed by the Pinkfong, a South Korean media startup. The song has become viral over children and adults alike. This research is undertaken to find out; the composer’s attitudes, the social relation among the participants, and the context of the situation in the discourse. The object of the study is obtained from the whole lyrics. Then it is analyzed through Appraisals and Critical Discourse Analysis by connecting every single line to the intentional marketing and social context. Finally, the conclusion shows that “Baby Shark” is a song about local wisdom education in Korea. The composer implicitly admires the shark and uses it as metaphor of Korean people mindset. The composer intends to give his full support and persuades the listener about hard working culture in Korea

Full textAbstract:
Using the case of female marriage migrants in South Korea, one new immigrant destination hosting the majority of East Asia’s marriage migrants, this article examines the associations between social participation, place of residence, and support network patterns among the six largest migrant groups ( n = 64,972): ethnic Koreans (Korean Chinese) born in China, Vietnamese, Han Chinese from China, and those from the Philippines, Japan, and Cambodia. The results show that both participation in community meetings and membership in non-governmental organizations are significantly associated with more types of Korean support networks and co-ethnic support networks, after controlling for demographics, immigrant characteristics, marital status, health status, perceived discrimination, and ethnicity or country of origin. Using Seoul City as a reference location, those who lived in Jeolla Province were less likely to have support networks composed of Koreans yet were more likely to have support networks of co-ethnics, after holding all other covariates constant. With the identification of significant interactions between marriage migrants’ place of residence and ethnicity, stratified ordered logistic models demonstrate how place of residence matters for marriage migrants of certain ethnicities or countries of origin. In conclusion, this article demonstrates the importance and the benefits of social participation for marriage migrants as a pathway to building support networks of local people and co-ethnics.

Full textAbstract:
Over a few decades, Korean diet has changed from traditional diet, mainly composed of rice and vegetables, to Westernised diet rich, in meat and milk, along with the economic development and globalisation. Increasing prevalence of diet-related chronic diseases such as cancer and metabolic syndrome (MetS) is becoming a heavy burden to society and requires further attention. In this review, the association of meat and milk consumption with cancer and MetS among Koreans was discussed. Previous meta-analyses showed that meat intake was positively associated with increased risk of cancers, especially colon, as well as obesity and type 2 diabetes mellitus, and that the intake of milk and dairy products was negatively associated with colorectal cancer, obesity, and type 2 diabetes mellitus, based on studies conducted mostly in Western countries. In Korea and other Asian countries, the association of meat and milk intake with cancers were inconclusive and varied by types of cancers. Conversely, milk intake was negatively associated with MetS risk as reported in Western countries. The difference in results between Korea and Western countries might come from the differences in dietary patterns and study designs. Most Koreans still maintain traditional dietary pattern, although rapid change towards Westernised diet is underway among the younger age group. Randomised clinical trials or prospective cohort studies with consideration of combined effects of various dietary factors in Korea and other Asian countries are needed to elucidate the impact of meat and milk or related dietary patterns in their diet.

Full textAbstract:
Ancient, ornately carved palaces in the midst of a megalopolis, the spirituality of delicate green Koryo celadon, an archaic traditional music as pungent (and delicious) as kimchi – once experienced, never forgotten. Add to these the city of Kyongju, called the ‘museum without walls’, the many reminders of a long history of suffering under Japanese oppression and the uninterrupted excellence of its poetry and visual arts, and one begins to feel Korea's special quality. The country is prosperous; education in all fields, including the arts, is given high priority. Contemporary life is vibrant and intense; the people possess a seemingly boundless capacity for hard work as well as for celebration, festivity, ceremony and mourning – and for music-making. Hardly surprising, then, that the compositional scene in the Republic of South Korea is booming, to say the least.

"The Bibliometric Keywords Network Analysis of Human Resource Management Research Trends: The Case of Human Resource Management Journals in South Korea." Sustainability 12, no. 14 (July 15, 2020): 5700. http://dx.doi.org/10.3390/su12145700.
Full textAbstract:
Although previous studies on human resource management (HRM) research trends in the global context provided very useful information about the structures of HRM research trends, they have critical limitations. Despite the growing contribution and significance of HRM practices in Korea, a dominant group of scholars has rarely focused on what is going on in the research community in the country. To overcome the limitations and fill the gaps found in studies on the global HRM trends, the purpose of this study is to conduct the keyword network analysis investigating the semantic network structure composed of Korean HRM studies. A total of 1158 research papers published by three top peer-reviewed HRM journals in Korea that were published from 2007 to 2018 were analyzed. The result shows that the whole network structure of Korean HRM has a complex semantic structure that is socially constructed. Additionally, this study identified the top 10 prominent keywords and its ego-centric networks, and nine thematic clusters. By adopting keywords network analysis in bibliometric methods, this study provides an accurate structural interpretation of Korean HRM research practice to facilitate the sustainable development of the studies on the global HRM trends.

Full textAbstract:
The scale of damage caused by drought is on the rise in South Korea. The country has been experiencing a 4–6-year cycle of extreme droughts at a nationwide scale. From 2014–2015, South Korea suffered from its worst drought in the past 50 years. This study aims to provide an effective drought management policy by analyzing the Korean government's response to the 2014–2015 drought under the National Drought Management Framework, which is composed of four stages: prevention, preparedness, response, and recovery. The findings indicate that the Korean government effectively addressed the drought, yet there are no measures currently in place to cope with megadroughts that last for more than 5 consecutive years. Immediate attention is required to conduct research and introduce policies that will help in managing megadroughts. This paper takes an interdisciplinary approach to drought preparedness research in the context of megadroughts and proposes an efficient national drought management framework that involves engagement of relevant line ministries.

Full textAbstract:
This paper discusses the relationship between grammar as linguistic knowledge, as envisaged in Generative Grammar, and usage, the result of performance. In concrete, I analyze the use of Korean reflexives ‘caki’, ‘casin’, and ‘cakicasin’ by examining the occurrences of these reflexives in a 5-million-word Korean corpus, taken from a 10-million-word Korean corpus which is called “KOREA-1 Corpus”, compiled at Korea University (H. Kim and B. Kang 1996). This corpus is composed of various genres of Korean texts including 10% of spoken material. From the KWIC concordances of accusative forms of these reflexives, ‘cakilul, casin-ul, cakicasin-ul’, I examined whether a reflexive has a local antecedent or a long-distance antecedent. The result is that ‘caki’ is almost even in having local and long-distance antecedents, but ‘casin’ has more and ‘cakicasin’ has much more local antecedents. I also examined the thematic roles of the local antecedents of reflexives, which shows that ‘casin’ has relatively more Experiencer antecedents than ‘caki’ has, although in both cases Agent antecedents dominate. The outcome of this frequency analysis suggests that a tendency (probably not yet grammaticalized), or degree of “naturalness” is real and can be captured in the usage data provided that we have a sizable amount of material which can be handled in an efficient way as provided by the corpus linguistic method of the present day. At the least, the result of such an investigation can provide a solid base from which further theorizing may proceed.

Full textAbstract:
The elderly population in Korea is rapidly increasing. It is necessary to develop multi-faceted and complex interventions for prevention and delay of dementia, balance improvement, and physical activity, among the elderly living in the community. This study aimed to examine the effects of the cognitive/exercise dual-task program on cognitive function, health status, depression, and life satisfaction of the elderly living in the community. A quasi-experimental study design using a pretest-posttest control group was employed. The study included a total of 65 elderly participants (intervention: n = 32, control: n = 33) in Seoul, South Korea. The cognitive/exercise dual-task program as an intervention was composed of 20 sessions for a total of 10 weeks, held twice a week for about 50 min each session. Measures were general characteristics of study participants, the Korean version of Mini-Mental State Examination (MMSE-K), Korean elderly health status assessment tool, Korean version of Geriatric Depression Scale, and the elderly life satisfaction scale. Data were collected from October 2020 to March 2021. There were statistically significant differences on cognitive function, health status, depression, and life satisfaction between two groups. The cognitive/exercise dual-task program was an effective intervention for improving cognitive function, health status, and life satisfaction, and for decreasing depression of the elderly living in the community. Health care providers need to pay attention to cognitive/exercise dual-task programs for elderly living in the community.

Full textAbstract:
Historically, South Korean society has been deeply influenced by Confucianism, which has an emphasis on the traditional family structure. If a given family does not belong in the “traditional” norm, which is composed of husband, wife, and children, they are often discriminated against and ostracized. Despite the increasing number of nonmarital cohabiters in South Korea, research is still insufficient to understand the phenomenon. This study explores the prevalence of nonmarital cohabitation in South Korea, which is still met with discrimination. Online surveys and in-depth interviews were conducted with cohabiters to gain an understanding of the phenomenon and to explore their marriage and family values. The findings of this study indicate that cohabiters who chose cohabitation as an alternative to marriage had more progressive values. Findings from the study provide implications for practice and policy.

Full textAbstract:
A large rapakivi granite batholith in the Neo-Archaean/Palaeoproterozoic Odesan complex, northeastern Gyeonggi massif, South Korea, has been dated at 1839±10 Ma using SHRIMP U–Pb analysis of zircons. The age, petrological and geochemical characteristics of this batholith are similar to those of the rapakivi granite batholiths exposed in the Rangnim massif of North Korea and in the Miyun–Chengde complex of North China. The country rocks of these rapakivi granite batholiths are also comparable; all are composed of granitic gneisses and banded iron formation (BIF)-bearing supracrustal rocks metamorphosed to amphibolite- to granulite-facies. This study provides new evidence for the suggestion that the Gyeonggi and Rangnim massifs may share an affinity with the Precambrian basement of the North China craton. The study provides new insight into the possible eastward extension of the Sulu orogenic belt in the Korean peninsula and further provides evidence to correlate the Korea basement to a possible global 2.1–1.8 Ga supercontinent.

The International Journal Of Alcohol And Drug Research, 5(2), 65-71. doi:http://dx.doi.org/10.7895/ijadr.v5i2.220Objective: Drinking-related problems are increasing among Asian immigrants despite the popular perceptions of a “model minority.” Sociocultural factors may relate to differing drinking patterns among subsets of Asian American populations. This study explores the relationship between nationality and alcohol consumption among Chinese and Korean Americans, specifically in regards to acculturation and social networks.Method: First-generation Chinese and Korean immigrants residing in the greater Los Angeles area were recruited (N= 2715). Structured interviews were conducted over the phone and by professional bilingual interviewers in the language of participant preference.Results: Although subsamples were demographically similar, Chinese immigrants were less likely to report heavy episodic drinking (HED) than Korean immigrants. Participants in each group with social networks composed of drinkers or problem drinkers and those that encouraged drinking were more likely to report HED themselves.Conclusions: Alcohol consumption and its dynamics are impacted by peer networks among first-generation Chinese and Koreans residing in the United States. While drinking behaviors differ for Chinese and Korean immigrants, the impact of peer’s drinking behaviors on one’s own drinking is paramount. This result has important implications for interventions and the need for further research focusing on the impact of peer interactions and alcohol use among this population.

Full textAbstract:
The purpose of this paper is to examine the historical and ideological positions of the Chikchi, a Korean Zen text. Originally composed of two fascicles, the book was published with metal type in 1377 and in woodblock print in 1378. The metal type print only remains. in its second fascicle, which is currently preserved in the La Bibliotheque nationale de France, registered in the Memory of the World by the United Nations, Educational, Scientific and Cultural Organization (UNESCO) Memory of the World list. However, the woodblock print remains in two fascicles, including the teachings of Buddhas, recorded sayings, enlightened verses, and transmission records of more than one hundred patriarchs and masters of India, China, and Korea. The role of the Chikchi shines more in modern times. As a rare book in Korea and as the oldest extant book printed with metal type in the world, it has a great significance in the world history of printing culture. The Chikchi also has originality in terms of soteriology, ideological flexibility, an open interpretation of Buddhist teachings, and an integration with Confucianism, thus suggesting its possible contribution to a better understanding of the characteristics of Korean Buddhism in particular and, by extension, East Asian Buddhism in general.

Full textAbstract:
In ancient Korea, pufferfish were called “복” or “복어,” whereas they have been called “hétún” (河豚) since the Ming dynasty in China, and were called “fugu” in ancient Japan. Since the introduction of the Chinese term “hétún” (河豚) into Korean and Japanese, pufferfish in Korea, China, and Japan have all been named “河豚.” Besides “하돈” (the Korean pronunciation of 河豚), pufferfish have been given various designations, such as the following: “후태” (鯸鮐) or “반어” (斑魚) based upon body patterns; “후이” (鯸鮧)” or “호이” (鰗鮧) by shape; and “기포어” (氣泡魚), “취두어” (吹肚魚), and “布久” by the look of its swollen belly. Other designations, such as “검돈” (黔魨), “작돈” (鵲魨), “활돈” (滑魨), “とらふぐ,” “からす,” and “ヒガンフグ,” were derived from pufferfish species, and designations like “진어” (嗔鱼) and “てっぽう” that originated from their habit also exist. As above, “복어” has various designations in each of the three countries, Korea, China, and Japan. These designations, composed of Chinese characters, influenced the others, and each country and ethnic group helped to form or transform new vocabularies. In particular, numerous terms concerning object designations in the forms of Chinese characters reveal hidden definitions of the ethnic groups and cultures in these designations. This study is focused on puffer designations in Korea, China, and Japan, how the puffer was named in each country from ancient through to modern times, and where the designations originated, and tries to determine the characteristics of each country’s puffer designations through investigation of the species and types of “pufferfish.”

Full textAbstract:
Purpose The purpose of this paper is to develop an equilibrium displacement model (EDM) that is able to evaluate the impacts of a free trade agreement (FTA) on the profits of farmers. Empirical applications of the developed EDM are performed for evaluating the influences of Korea-Chile FTA on the grape industry in Korea. Design/methodology/approach Supply and demand equations together with profit function of individual farmers are converted into log-differential forms that compose the EDM. The cost function of grape producers is estimated for deriving the parameters that are required in applying the developed EDM. Findings The share of profit within revenue and the elasticity of cost with respect to quantity in the cost function play key roles in assessing the change in farmers’ profit. The empirical assessment of the effects of Korea-Chile FTA indicates that this FTA has little impact on the Korean grape market and grape producers in Korea. Originality/value Usefulness of the existing EDM has been limited in evaluating the impacts of exogenous shocks on the individual farmer level. This paper fills this gap by developing an EDM that assesses the impacts of tariff reduction on farm-level profit.

Full textAbstract:
Endovascular recanalization therapy (ERT) has been a standard of care for patients with acute ischemic stroke due to large artery occlusion (LAO) within 6 hours after onset since the five landmark ERT trials up to 2015 demonstrated its clinical benefit. Recently, two randomized clinical trials demonstrated that ERT, even in the late time window up to 16 hours or 24 hours after last known normal time, improved the outcome of patients who had a target mismatch defined as either clinical-core mismatch or perfusion-core mismatch, which prompted the update of national guidelines in several countries. Accordingly, to provide evidence-based and up-to-date recommendations for ERT in patients with acute LAO in Korea, the Clinical Practice Guidelines Committee of the Korean Stroke Society decided to revise the previous Korean Clinical Practice Guidelines of Stroke for ERT. For this update, the members of the writing group were appointed by the Korean Stroke Society and the Korean Society of Interventional Neuroradiology. After thorough reviewing the updated evidence from two recent trials and relevant literature, the writing members revised recommendations, for which formal consensus was achieved by convening an expert panel composed of 45 experts from the participating academic societies. The current guidelines are intended to help healthcare providers, patients, and their caregivers make their well-informed decisions and to improve the quality of care regarding ERT. The ultimate decision for ERT in a particular patient must be made in light of circumstances specific to that patient.

Full textAbstract:
In March 2010, a North Korean submarine fired a torpedo against the South Korean ship Cheonan, which resulted in the deaths of 46 sailors. Is its surprise attack justified? The academic examination has rarely been made over whether North Korea’s use of military force is justified in this battle. As the just war theory to date has dealt mostly with major wars, it also can guide us to judge whether this limited warfare is just or not. The just war principles are composed of three axes: before, in and after wars. First, North Korea’s provocation had neither right cause nor right intension because it attacked the Cheonan preventively, not preemptively, and was intended to achieve its domestic objective, the stable succession of the Kim regime. Second, North Korea also did not observe in-war principles in the sense that it attacked and sank the Cheonan unproportionally to maximize the effectiveness of revenge. Third, North Korea was not interested in post-battle settlements but intended to aggravate tensions in the region, which is not compliant with post-war principles. The examination sheds some light on the need to expand the scope of just war principles from war to limited warfare and battles particularly in the sense that it helps restrain unethical warfare and maintain the rules-based international order. This expansion also will contribute to not only the richness of the just war theory but also further leading it to evolve into a grand theory of war.

Full textAbstract:
The crustose brown algal genus Endoplura has been known as a monotypic genus characterized by its intercalary plurangial reproductive structures composed of 2–4 separate parallel filaments terminated by 2–5 sterile cells and by containing several to many chloroplasts per cell. In this study, Endoplura jejuensis sp. nov. and E. koreana sp. nov. from Korea are newly described based on molecular and morphological analyses. Our phylogenetic analyses of the rbcL gene reveal that E. jejuensis sp. nov. and E. koreana sp. nov. are placed in the same clade with “E. aurea” from Japan with a strong bootstrap supporting value. E. jejuensis is characterized by small and light to dark brown crustose thalli of less than 1 cm diameter, tufts of hairs arising from the basal disc, plurangia composed mostly of two separate parallel reproductive filaments terminated by 2–4 sterile cells, and sessile unangia each with a single paraphysis. E. koreana is distinguished by olive or yellowish-brown crustose thalli of up to 3 cm diameter, tufts of hairs arising from the basal disc, and apical parts of erect filaments, plurangia with 2–5 separate reproductive filaments terminated by 2–8 sterile cells, and sessile unangia with 1–2 paraphyses. Our studies also show that “E. aurea” specimens from Japan may be recognized to be a different species from other Endoplura species.

The car body of the bi-modal tram has been designed and built to have low floor to provide the old and the handicapped with easy access considering Korean physical standard, passenger capacity (standee, seated, handicapped), and bus and urban railway regulations in Korea. The car body has been composed of composite materials (light-weight sandwich constructions) with glass epoxy skins, aluminum honeycomb cores and aluminum inner-frames. This paper was aimed to evaluate dynamic characteristics of the car body while the bi-modal tram was running in the test track. Based on the results from vibration accelerations measured on the floor level of centers of car bodies and axle, dynamic characteristics of the composite materials car body were discussed in this paper.

Full textAbstract:
In this study, we examine the role of mutual trustworthiness between labour representatives and management and its relationship with the adoption of High Performance Work Systems (HPWS) in the Korean employment relations context. We argue that trustworthiness is a feature of the parties to the exchange, as opposed to trust, which explains the nature of exchange relationships. We follow existing literature on trustworthiness and agree that it is composed of three variables, i.e., ability, integrity, and benevolence. We test the effects of these three variables as important antecedents for the adoption of HPWS at the workplace level. Using the National Establishment Survey 2009 conducted by Statistics Korea as a sample frame, we survey a representative sample of Korean establishments. These data consist of 1,353 paired responses from labour representatives and managers.Our results show that labour-management mutual ability trustworthiness (MAT) has a positive and significant relationship with the adoption of high performance work systems (Hypothesis 1); mutual benevolence trustworthiness (MBT) has a positive and significant relationship with the adoption of high performance work systems (Hypothesis 2); and mutual integrity trustworthiness (MIT) has a positive and significant relationship with the adoption of high performance work systems (Hypothesis 3). These results show that mutual trustworthiness in Korean employment relations is an important antecedent for the adoption of HPWS and can enable Korean industry to improve its position in the global economy. In the final analysis, it is implied that employment relations actors pursuing cooperative employment practices should ensure the development of a virtuous cycle of mutual trustworthiness.

The purpose of this study was to validate the Thriving at Work Scale(TWS) developed by Porath and colleagues(2012) in Korea. Specifically, the study was attempted to (1) examine the factor structure and items of the TWS to develop the Korean version of the TWS(TWS-K), and (2) investigate the discriminant validity of the TWS-K with the 5 similar concepts proposed only conceptually in the literature(job engagement, flow, resilience, flourishing, psychological well-being) as well as the incremental validity of the TWS-K over job engagement on performance. Two surveys were conducted for this purpose, and a total of 850 employees working at different fields in Korea participated in off-line or on-line survey. In Study 1, we conducted both exploratory and confirmatory factor analyses using the off-line data of 205 participants. The results showed that the factor structure of vitality and learning composed of positive 10 items in the TWS-K had a better fit compared to the original positive 8 and negative 2 items included in the TWS. It was also found that the reliability of the TWS-K was much higher than that of the TWS among Koreans. In Study 2, the results of a confirmatory factor analysis on 645 on-line participants demonstrated the six-factor model which assumed the independence of 6 related factors had the best fit among 6 models, supporting the discriminant validity of the TWS-K. Support was also found for the criterion-related validity of the TWS-K on the various criteria of performance. In addition, the results of hierarchical multiple regression analyses confirmed that thriving at work is a distinct construct, as the incremental variances of thriving at work on task, contextual, and adaptive performance were significant when each of similar concepts such as jog engagement controlled. Finally the implications and future research directions were discussed based on the findings.

Full textAbstract:
An optimal design model for residential photovoltaic (PV) systems in South Korea was proposed. In the optimization formulation, the objective function is composed of three costs, including the monthly electricity bill, the PV system construction cost (including the government’s subsidy), and the PV system maintenance cost. Here, because the monthly electricity bill is not differentiable (it is a stepped piecewise linear function), it cannot be solved by using traditional gradient-based approaches. For details considering the residential electric consumption in a typical Korean household, consumption was broken down into four types (year-round electric appliances, seasonal electric appliances, lighting appliances, and stand-by power). For details considering the degree of PV generation, a monthly generation dataset with different PV tilt angles was analyzed. The optimal design model was able to obtain a global design solution (PV tilt angle and PV size) without being trapped in local optima. We hope that this kind of practical approach will be more frequently applied to real-world designs in residential PV systems in South Korea and other countries.

In this article we offer an analysis of the internal structure of the so-called indefinite/existential quantifiers in Korean. For this purpose, we will first try to establish the existence of the hitherto unidentified question marker in Korean, namely, the "self-addressed" question marker -ka. Second, we will argue, on the basis of the analysis, that the indefinite/existential quantifiers in Korean are actually composed of a wh-expression plus a self-addressed question marker at some level of representation. We will provide supporting evidence from Middle Korean and Kyengnam dialect as well as from Modern Standard Korean. In the first part of this paper, we will identify a new type of question marker -ka, which marks a question addressed to the speaker him/herself as opposed to one directed to the hearer. In the second part of this paper, we will argue that the indefinite quantifiers in Korean are actually composed of a wh-word plus a self-addressed question marker -ka.

Full textAbstract:
Globalised neoliberalism does not unify urbanisation processes but rather varies according to local contexts. This article explores the unique neoliberalisation process in large urban developments that have contributed to Seoul becoming a global city. Not only has the formal process of privatisation been important but also the vernacular practice of the ordinary people has informally grown during the process. By establishing a matured market of the mass production and consumption of high-rise apartments since the 1970s, more than half of the housing stock is now composed of high-rise apartments in South Korea. Gangnam represents the wealthiest district shifting from rural sites to highly dense urban areas due to their large-scale high-rise developments. Not only have societal changes made way for super-high-density apartment complexes as a rational response to population and economic growth, high-rise developments have also allowed Seoul to grow its population and expand its spatial footprint. Because of the dominance of universal western knowledge, this phenomenon has not been fully understood. While neoliberalism has been broadly adopted, the actual development process in Korea is distinctive not only from the West but also the East. The article argues that ‘vernacular neoliberalism’ has evolved not just by the formality of the ideological market system but also by the informality of survival practices of Korean lives largely under the colonial period and the aftermath of the Korean War. It particularly shows how large urban developments have been widespread by integrating a vernacular private rental system called chonsei into the formal structure.

Full textAbstract:
In this work, we examine poverty among vulnerable Korean female householders using a multidimensional concept with six dimensions: money, health, housing, employment, human relations, and social security. Taking data from the “Korea Welfare Panel Study 2015” by the Korea Institute for Health and Social Affairs and the Welfare Research Institute of Seoul National University, we apply latent class analysis to assess poverty among female householders using the Mplus8 software. The poverty indicator correlations are examined with Cramer’s V, and the differences in individual characteristics are analyzed through X2 and analysis of variance. The results show that the poor are composed of several groups with different characteristics. We divide the female householders into three main types, all likely to experience poverty in terms of money and employment. However, Type 1 shows a high probability of experiencing poverty in terms of money, employment, human relations, and health; when compared with Types 2 and 3, Type 1 poverty probability turns out to be higher for several indicators. Type 2 shows susceptibility to basic poverty, with a high probability of experiencing poverty in terms of money and employment. Lastly, Type 3 has a higher probability of health poverty than Types 1 and 2.

Full textAbstract:
The atherogenic index of plasma (AIP), composed of triglycerides and high-density lipoprotein cholesterol, is a novel critical marker for assessing the risk of atherogenicity and cardiometabolic health. We aimed to prospectively study the association between AIP and incident ischemic heart disease (IHD) risk in a large cohort of non-diabetic Korean adults. Data were assessed from 17,944 participants without diabetes from the Health Risk Assessment Study (HERAS) and Korea Health Insurance Review and Assessment (HIRA) data. The participants were divided into four groups according to AIP quartiles, calculated as log (triglyceride/high-density lipoprotein cholesterol). We prospectively assessed hazard ratios (HRs) with 95% confidence intervals (CIs) for IHD using multivariate Cox proportional-hazard regression models over a 50-month period that followed the baseline survey. During the follow-up period, 332 participants (1.9%) developed IHD. HRs of IHD for AIP quartiles 2–4 were 1.58 (95% CI, 1.03–2.43), 1.82 (95% CI, 1.20–2.78), and 2.11 (95% CI, 1.37–3.24) after adjusting for age, sex, body mass index, smoking status, alcohol intake, physical activity, mean arterial blood pressure, fasting plasma glucose, high-sensitivity C-reactive protein level, and hypertension medication. Higher AIP levels may precede and predict the development of IHD in non-diabetic Korean adults.

Abstract Objectives Frailty is a clinical syndrome in older adults. Adequate nutrition is a modifiable factor in preventing frailty. The purpose of this study was to investigate the association between frailty and dietary intake in Korean elderly. Methods This study used raw data from the 2018 Korea National Health and Nutrition Examination Survey. Study subjects were 1268 (535 of men and 733 of women). Frailty was defined as having three or more of the following five criteria including unintentional weight loss, weakness, waking difficulties, exhaustion and low physical activity. Pre-frail was defined as having one or two criteria. Robust was defined as having none of the criteria. Dietary intake was assessed by a one-day 24 h dietary recall. The food variety score (FVS) was defined as the number of food items consumed by each subject during the last 24 h. Results In this study, 9.7% of men and 21.9% of women were classified as frail group. Intake of energy, macronutrients and micronutrients was significantly low in frail men and women. Also, total food intake was significantly low in frail men and women. In men, the odds ratio (95% CI) of frailty for those in the highest tertile compared with the lowest tertile of food intake were 0.34 (0.13–0.93) for fruits. In women, the odds ratio (95% CI) of frailty for those in the highest tertile compared with the lowest tertile of food intake were 0.57 (0.35–0.93) for potatoes and 0.55 (0.30–0.99) for fish and shellfish. In addition, subjects with higher mushroom intake had lower risk of frailty 0.31 (0.12–0.78) in consumer and 0.41 (0.22–0.79) in non-consumer after adjustment for all potential covariables. Conclusions These results suggested that diverse diets composed with five major food groups may have preventive effect against the risk of frailty among Korean elderly.

Full textAbstract:
The Muscat Bailey A (MBA) grape, one of the most prominent grape cultivars in Korea, contains considerable amounts of monoterpene alcohols that have very low odor thresholds and significantly affect the perception of wine aroma. To develop a potential wine starter for Korean MBA wine, nine types of non-Saccharomyces yeasts were isolated from various Korean food materials, including nuruk, Sémillon grapes, persimmons, and Muscat Bailey A grapes, and their physiological, biochemical, and enzymatic properties were investigated and compared to the conventional wine fermentation strain, Saccharomyces cerevisiae W-3. Through API ZYM analysis, Wickerhamomyces anomalus JK04, Hanseniaspora vineae S7, Hanseniaspora uvarum S8, Candida railenensis S18, and Metschnikowia pulcherrima S36 were revealed to have β-glucosidase activity. Their activities were quantified by culturing in growth medium composed of different carbon sources: 2% glucose, 1% glucose + 1% cellobiose, and 2% cellobiose. W. anomalus JK04 and M. pulcherrima S36 showed the highest β-glucosidase activities in all growth media; thus, they were selected and utilized for MBA wine fermentation. MBA wines co-fermented with non-Saccharomyces yeasts (W. anomalus JK04 or M. pulcherrima S36) and S. cerevisiae W-3 showed significantly increased levels of linalool, citronellol, and geraniol compared to MBA wine fermented with S. cerevisiae W-3 (control). In a sensory evaluation, the flavor, taste, and overall preference scores of the co-fermented wines were higher than those for the control wine, suggesting that W. anomalus JK04 and M. pulcherrima S36 are favorable wine starters for improving Korean MBA wine quality.

Full textAbstract:
Abstract Since 2009, the Korea Meteorological Administration (KMA) has participated in ground validation (GV) projects through international partnerships within the framework of the Global Precipitation Measurement (GPM) Mission. The goal of this work is to assess the reliability of ground-based measurements in the Korean Peninsula as a means for validating precipitation products retrieved from satellite microwave sensors, with an emphasis on East Asian precipitation. KMA has a well-developed operational weather service infrastructure composed of meteorological radars, a dense rain gauge network, and automated weather stations. Measurements from these systems, including data from four ground-based radars (GRs), were combined with satellite data from the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) and used as a proxy for GPM GV over the Korean Peninsula. A time series of mean reflectivity differences (GR − PR) for stratiform-only and above-brightband-only data showed that the time-averaged difference fell between −2.0 and +1.0 dBZ for the four GRs used in this study. Site-specific adjustments for these relative mean biases were applied to GR reflectivities, and detailed statistical comparisons of reflectivity and rain rate between PR and bias-adjusted GR were carried out. In rain-rate comparisons, surface rain from the TRMM Microwave Imager (TMI) and the rain gauges were added and the results varied according to rain type. Bias correction has had a positive effect on GR rain rate comparing with PR and gauge rain rates. This study confirmed advance preparation for GPM GV system was optimized on the Korean Peninsula using the official framework.

Full textAbstract:
Hanok is a building style in Korean traditional architecture that presently supports a specialty of urban scenery and residential environment for regeneration in Korea. However, it is difficult to review or evaluate for the performance of Hanok, and there is no definite standard that can be applied to it yet. Therefore, it is necessary to establish the evaluation system of the residential performance of Hanok, and its concept model of the habitability performance needs to be derived in order to develop an evaluation system for the residential performance of Hanok. For this study, its evaluation factors have been classified into three major aspects such as the architectural space, the village complex, and the sustainability. This study, then, has attempted to build an evaluation system composed of proven assessment items or factors and performed AHP (Analytic Hierarchy Process) analyses with certified experts in the Hanok field and applied the relative importance among the evaluation items. Finally, this research has proposed an evaluation model of the habitability performance of Hanok. As a result of applying the assessment model for weighted habitability performances, the proposed evaluation system has been implemented as the inherent value of Hanok and its objectivity to be a major sustainable form of regeneration for contemporary residency in Korea.

PurposeThe National Health Insurance Service (NHIS)-Senior was set up to provide high-quality longitudinal data that can be used to explore various aspects of changes in the socio-economical and health status of older adults, to predict risk factors and to investigate their health outcomes.ParticipantsThe NHIS-Senior cohort, a Korean nationwide retrospective administrative data cohort, is composed of older adults aged 60 years and over in 2002. It consists of 558 147 people selected by 10% simple random sampling method from a total of 5.5 million subjects aged 60+ in the National Health Information Database. The cohort was followed up through 2015 for all subjects, except for those who were deceased.Findings to dateThe healthcare utilisation and admission rates were the highest for acute upper respiratory infections and influenza (75.2%). The age-standardised (defined with reference to the world standard population) mortality rate for 10 years (through 2012) was 4333 per 100 000 person-years. Malignant neoplasms were the most common cause of death in both sexes (1032.1 per 100 000 person-years for men, 376.7 per 100 000 person-years for women). A total of 34 483 individuals applied for long-term care service in 2008, of whom 17.9% were assessed as grade 1, meaning that they were completely dependent on the help of another person to live daily life.Future plansThe data are provided for the purposes of policy and academic research under the Act on Promotion of the Provision and Use of Public Data in Korea. The NHIS-Senior cohort data are only available for Korean researchers at the moment, but it is possible for researchers outside the country to gain access to the data by conducting a joint study with a Korean researcher. The cohort will be maintained and continuously updated by the NHIS.

Background:Due to the shared mechanism of nontraumatic avascular necrosis (AVN) and endothelial dysfunction, the associations of AVN with increased cardiovascular and cerebrovascular events have been suggested in the several population-based studies.Objectives:This study aimed to estimate the prevalence and incidence of nontraumatic AVN in South Korea from the Korean National Health Insurance Service Sample Cohort Database 2.0 (2006-2015) and to evaluate the risk of major cardiovascular and cerebrovascular events among patients with nontraumatic AVN.Methods:We defined an incident case as a newly diagnosed and registered patient in the registry in that year, with a 2-year washout period. Prevalent cases were defined as all patients with nontraumatic AVN in the corresponding year. To evaluate the cardiovascular and cerebrovascular risks in patients with AVN, we set AVN group composed of patients with an initial diagnosis of non-traumatic AVN between 2008 and 2010 (n=1,150). The comparison group was composed of randomly selected subject (5 per patient with AVN; n = 5,750) who were matched to the AVN group according to age, sex, resident area, and year of AVN diagnosis. The development of major cardiovascular and cerebrovascular events was tracked in each sampled patient until 2015. Cox proportional hazard regressions were used to calculate the overall risks for the development of major cardiovascular and cerebrovascular events.Results:From 2008 to 2015, the prevalence of nontraumatic AVN increased gradually, but its incidence did not change, with an annual average incidence of 413 per 1 million population and the male-to-female ratio of 1.2:1. The peak incidence occurred in the 50-59 year age group. The incident AVN was more prevalent in male than in female under 70, but there was female predominance after the age of 70 (Figure 1). The patients with AVN had a higher cumulative incidence of major adverse cardiovascular and cerebrovascular events than controls (19.5% versus 14.9%; p = 0.017). Upon univariate Kaplan-Meier method with the log-rank test, there was a significant difference in major cardiovascular and cerebrovascular events-free survival rates between AVN group and control group (p <0.001). However, after adjusting for potential confounders including hypertension, diabetes, dyslipidemia, and use of steroid or statin, the association between AVN group and major adverse cardiovascular and cerebrovascular events was insignificant (adjusted HR 1.114, 95% CI 0.959-1.295, p=0.158)Conclusion:In this population-based cohort study, we provided the updated epidemiologic data of Korean patients with nontraumatic AVN. The increased risk for major cardiovascular and cerebrovascular events among AVN patients was not observed in the representative Korean population.References:[1]Kang JH, Lin HC.

Full textAbstract:
Although Korea has made notable progress in the availability of public rental housing, Korea’s public rental housing representing 6.3% of the country’s total housing is still below the 8% OECD average from 2016. The Seoul Metropolitan Area (composed of Seoul City, Incheon City, and Gyeonggi Province) has nearly 50% of the country’s population, but 11% of the nation’s territory, meaning the area suffers from an acute shortage of public rental housing. This is a serious problem which is hampering the sustainability of Korean society in general. We will examine the possibility of improving this public housing problem using certain algorithms to optimize decision making and resource allocation. This study reviews two pioneering studies on optimal investment portfolio for land development projects and optimal project combination for urban regeneration projects, and then optimizes a public housing investment combination to maximize the amount of public rental houses in Gyeonggi province using optimization techniques. Through the optimal investment combination, public rental houses were found to be more efficiently and sustainably planned for the community.

Objectives: The aim of this study was to explore factors that influenced decision making in the assessment of new health technology in Korea.Methods: We analyzed the decision-making results of the Committee for New Health Technology Assessment (CnHTA) on fifty-three new nondrug health technologies in Korea from July 2007 to December 2010. The scope of the committee was mainly limited to safety and efficacy/effectiveness, and every decision was based on a systematic review of the literature. The committee was composed of healthcare professionals, policy makers, lawyers, and representatives from nongovernmental organizations. Decisions made on therapeutic interventions were included, while those on diagnostic procedures were excluded.Results: Factors that positively influenced decisions were lower complication rate than existing technology, similar or greater effectiveness compared with existing technology, ability to save critical organs, absence of alternative intervention, decreased invasiveness, expansion of patient's set of choices, and similarity to the mechanism of existing technology. Factors that negatively influenced decisions were higher complication rates than existing technology, lower effectiveness than comparable technology, low levels of evidence, unknown mechanisms of intervention, inconsistency, lack of long-term outcomes, lack of comparative data, nonstandardized technology, heterogeneity between control and treatment, excessively diverse indications, and nongeneralizability.Conclusions: This qualitative analysis of past decision-making results provided us with clues on the values that decision makers on the Korean CnHTA considered in terms of safety and effectiveness. These findings will help us develop appraisal guidelines and enhance the objectivity of decision-making processes in Korea.

Full textAbstract:
This paper reviews the taxonomy, evolution and phylogeographic aspects of the genus Helonias L. sensu lato, including Ypsilandra and Heloniopsis (Melanthiaceae) that are basically similar in many morphological and ecological characters to Helonias sensu stricto. It includes three parts, I–III. In Part I, characters and their variation are examined to determine generic traits and diversity. In Part II, an attempt is made to taxonomically determine diversity among individuals. Taxonomic conclusions and revisions are principally the following: Helonias comprises 12 species, which are classified into two sections, H. sect. Helonias and H. sect. Heloniopsis comb. & stat. nov. Helonias sect. Helonias consists of H. bullata only; H. sect. Heloniopsis comprises two subsections, H. subsect. Ypsilandra comb. & stat. nov. and H. subsect. Heloniopsis. Helonias subsect. Ypsilandra is composed of five species previously published under the genus Ypsilandra. Helonias subsect. Heloniopsis consists of two series, H. ser. Umbellatae ser. nov., with three species from Taiwan and the Nansei Islands (incl. the Ryukyus), Japan, and H. ser. Heloniopsis, with three species from Japan, Korea and E. Russia (southern Sakhalin). Helonias yunnanensis var. mesostyla is described as a new variety from N Myanmar and SW China (NW Yunnan). The new combinations Helonias koreana (from Korea) and H. parviflora (from China) are proposed. Lectotypes for Ypsilandra parviflora, Y. thibetica, Y. yunnanensis var. micrantha, Heloniopsis breviscapa and H. grandiflora are designated. A revised typification for Sugerokia japonica is proposed, negating a previous lectotypification. Heloniopsis tubiflora is reduced to synonymy under Helonias koreana. In Part III, the evolutionary and phylogeographic aspects of Helonias are discussed, and a phylogram inferred from cladistic analysis of phenotypic characters is presented. In the phylogram, Helonias is monophyletic, while H. sect. Helonias and H. subsect. Ypsilandra are respectively paraphyletic, and H. subsect. Heloniopsis is monophyletic. Incongruence in results between morphological and DNA sequence analyses is briefly discussed.

Abstract BACKGROUND There was no practical guideline for the management of patients with central nervous system (CNS) tumor in Korea for many years. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, started to prepare a guideline for CNS tumors from February 2018. METHODS The Working Group was composed of 35 multidisciplinary medical experts in Korea. References were identified through searches of PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL using specific and sensitive keywords as well as combinations of keywords. RESULTS First, for the glioblastoma as WHO Grade IV Gliomas, the maximal safe resection if feasible is recommended. Patients aged ≤ 70 years with good performance should be treated by concurrent chemoradiotherapy with temozolomide followed by adjuvant temozolomide chemotherapy (Stupp’s protocol) or standard brain radiotherapy alone. However, those with poor performance should be treated by hypofractionated brain radiotherapy (preferred) ± concurrent or adjuvant temozolomide or temozolomide alone (Level III) or supportive treatment. Second, for the WHO Grade III Gliomas, patients with anaplastic astrocytoma, IDH-mutant should be treated by standard brain radiotherapy followed by adjuvant temozolomide chemotherapy, or Stupp’s protocol, or standard brain radiotherapy with neoadjuvant or adjuvant PCV chemotherapy, or Standard brain radiotherapy alone (Level III). However, those anaplastic astrocytoma, IDH-wildtype should be treated by the protocol for glioblastoma. Third, for the WHO Grade II Gliomas, patients with diffuse astrocytoma, IDH-wildtype without molecular feature of glioblastoma should be treated by standard brain radiotherapy and adjuvant temozolomide chemotherapy (Level III), or standard brain radiotherapy alone, or observation. And patients with diffuse astrocytoma IDH-mutant and oligodendroglioma (IDH-mutant and 1p/19q codeletion) should be treated according to the risk factors. CONCLUSION The recent KSNO’s guideline recommends that glioma should be treated according to the molecular as well as histological features. However, the practice can be limited by the National Insurance for Health in Korea.
